Driven by thirst, a wolf and a lamb had come to the same stream; the wolf stood above, and the lamb at a distance below. Then, the spoiler, prompted by a ravenous maw, alleged a pretext for a quarrel. "Why," Said he, "Have you made the water muddy for me while I am drinking?" The fleece-bearer, trembling, answered: "Prithee, wolf, how can I do what you complain of? the water is flowing downwards from you to where I am drinking." The other, disconcerted by the force of truth, exclaimed: "Six months ago, you slandered me." "Indeed," Answered 366 the lamb, "I was not born then." "By hercules," Said the wolf, "Then 'twas your father slandered me;" And so, snatching him up, he tore him to pieces, killing him unjustly. 
This fable is applicable to those men who, under false pretences, oppress the innocent.
